They Slandered Me and Left Me Hurt, So I Married Someone Else. Don't Cry Now

I’m an orphan of the Wei family, along with my older sister. Ever since we were young, my sister found medicine filthy and smelly, so Father passed down all his medical knowledge to me. She devoted herself instead to music, chess, calligraphy, and painting. While gathering herbs on a cliff to cure the Crown Prince’s chronic illness, I ended up covered in injuries. After he recovered, he accused me of being vain and stopping at nothing to get what I wanted. The Emperor had intended to marry me off to the Crown Prince, but the Crown Prince knelt for a long time and begged His Majesty to rescind the decree, because he had fallen for my kind and delicate older sister. In front of everyone, the Crown Prince mocked me, calling me scheming and unworthy of entering his Eastern Palace. He said that compared to my gentle, kind-hearted sister, I was like mud to the clouds. Later, I married the most powerful man in the land, dressed in red. But he stopped my bridal sedan at all costs and asked if I was the one who had saved him all those years ago.
